Specification of Letters Patent. Patented Aug. 17, 1915..

Application filed July 22, 1911. Serial No. 639,905.

To all whom it may concern Be 1t known that I, ALBERT A. PAGE, of

the town of East Haven, in the county of New Haven and State of Connecticut, have invented new and useful Improvements in Locks, of which'the following is a full, clear, and exact description, when taken in connection with the accompanying drawings, which form a part thereof.

This invention relates to locks and more particularly to hotel locks of the general type shown in the patent to William J Carroll, #898,434, dated Sept. 15, 1908. In locks of this kind there are two dead bolts directly operable respectively by keys'iinsertecl only at the inside and outside re spectively of the door, there being a connection between said boltswhereby the protraction of one when the other is protracted will retract the second named bolt, whereupon the first bolt may be retracted independently. The inside bolt carries award adapted to cooperate with the keyhole of the outside bolt when the inside bolt is protracted, in order to block the operation of the,

outside bolt by the ordinary change key though permitting the operation of the outside bolt by an emergency key.

One object of the'present invention is to provide a lock of the general character above stated having a sliding Ward associated with the keyhole of one (the outside) bolt, movable relatively to said bolt and adapted to be locked in blocking position thereby, so that after said bolt hasbeen protracted by a key, it cannot be retracted except by the same key or a key of the same order. In other words, the ward is locked in blocking position by the same bolt to which it relates, for the purpose of preventing the retraction of the bolt by a change key, for.

example, when it has emergency key contemplate the a ward or blocking single ward will fulfil the purpose of preventing the operation of one bolt (exceptby a certain key or keys) when the other bolt has been thrown, and of preventing the retraction of the first bolt other key of low order thrown or order.

been thrown by an provision of means whereby key blocking device is locked in when it has been protracted by a key of a higher More particularly, it is intended to or other special key. I also 5 position by both bolts, so that a by a change key or provide a ward or key'blocking device mov able with respect to'both bolts and adapted to be locked in blocking position with relation to the outside bolt when the inside bolt is thrown and to prevent the retraction of the outside bolt by a change key when it has been thrown by an emergency key.

The invention also consists in other novel features and combinations of parts, as will appear from the following description and claims.

Referring to the drawings, Figure l represents a side elevation-of a lock embodying the invention with the cap plate removed and both dead bolts shown in their retracted position, Fig. 2, a similar view with the inside bolt shown protracted by the guest key from the inside of the lock, Fig. 3, a

similar view with the outside bolt shown protracted by the guest key, Fig. 4:, a similar View of the lower portion of the lock with the outside bolt shown protracted by the emergency, key, and prevented from retraction by the guest key, Fig. 5, a similar view of the lower portion of the lock with both dead bolts shown retracted and the tumblers removed disclosing in full the emergency ward, Fig. 6, a similar view showing the outside guest key from the outside of the lock, Fig. 7, a similar view with the outside bolt protracted by the emergency key, Fig. 8, a similar View with the inside bolt protracted, Fig. 9, a reverse .view shown retracted, Fig. 10, the outside bolt protracted, Fig. 11, a similar View with the inside bolt shown protracted, Figs. 12 and 13, a transverse vertical sectionthrough the lower end of the tumblers and ward showing their relation to the emergency key and the guest key, respectively, Figs. 14, 15 and 16, detail views of the emergency, guest and master or chamber-maid key, respectively, and Fig. 17 a detail of the tumbler stump.

In all figures, similar letters of reference represent like parts. 7 In the drawings, the parts designated by the letter A-represent the case of a lock, and B its face plate through which is adapted to project the latch bolt C yieldingly protract ed by a coiled spring D surrounding the spindle of the latch bolt and engaging at one end the head of the latch bolt, and at the bolt protracted by the of the dead bolts a similar view with adapted to be engaged by a shoulder Pion case.

other end a stationary part E in the lock of a sliding yoke F actuated by the drawheadG, which is adapted to be operated by 7 the knob spindle H. A spring I returnsthe yoke F to its normal position.

- J designates a dead bolt adapted to be actuated by a key, which may be inserted through a key-hole K from the inside of the lock, and L designates a second dead bolt adapted to be actuated by a key from the outside of the lock. Between the dead bolts J and L a lever M is mounted on a post N in the casing, and the lever M engages at one' end a slot or opening Den the under side of the bolt J, as shownmore particularly in Figs. 9-11, and the under end of the lever is the upper side of the bolt L. By this construction when the bolt J is protracted, as

shown more particularly in Figs. 2 and 11,,

the lever M is rotated so that its lower end will abut against the shoulder P on the bolt L. Consequently, the protraction of the bolt L while the bolt J is protracted will necessarily retract the bolt J. On the other hand; when the bolt L is protracted, as shown more particularly in 'Figs. 3 and 10, the lever M is swung by the shoulder P to the position shown in Fig. 10, so that the protraction of the bolt J will necessarily'retract the bolt L. By this construction, the protraction of either bolt necessarily retracts the other bolt.

' ticularlyin Fig. 2,,whereby the protraction of the bolt J from the inside of the door will deadlock the latch bolt C from retraction by means of the knob spindle H, consequently when the door is locked from the inside the knob spindle H cannot be turned, and a chamber-maid or other person may ascertain if the door is locked from the inside by merely attempting to turn the knob, without the necessitv of inserting the key from the outside 01 the lock.

-Mounted in the casingto slide vertically to a limited extent is award S, consisting of a freely movable gravity actuated flat plate having an upper guide arm, guided by a lug S. This plate has an opening or slot T, for

the stump V carried by the tumbler of the outside bolt L. Projecting into the opening T from the edge of the ward S is a wedgeshaped projection or check U, which is adapted to engage the under side of the stump V when the bolt L is protracted without raising the ward S (see Fig. 7 If, however, the ward S is slightly raised before the bolt L is moved from its retracted to its protracted position (which action is effected by the engagement of the bit of either the key WV or key W with the lower edge of the The latch bolt is retracted by means" ward, the check U will engage the upper side v the outside bolt L is protracted by the emeron its under side by the check U of the ward tion shown in Figs. at and 7 Consequently,

. if, as shown more particularly in Figs. 4 and 13, the bit H of the guest key W, or the chamber-maid 'ormaster key W, isnot provided with a slot by which it can'pas's the ward S it will be impossible to rotate the guest key l/V,'or master key 7' to retract gency key X, so that the stump V is engaged S, the ward cannot be raised from thexposithe bolt L. The emergency key X, as shown more particularly in Figs. 12 and 1a, .is provided with a slot Z adapted to receive the ward S so that this key can be rotated even when the ward is in the, lower position shown in Figsla and 7 7 The ward S is not only locked in its blocking (lowermost) position by the outside bolt L when the latter is protracted by aneniergency key, but also by the protraction of the inside bolt J by any of the keys.

This is eliected by the movement of the stump D on the inside bolt over. a shoulder S at the upper part of the ward as said inside bolt is mov'ed'toits protracted position. 7

A designates one or more bolt tumblers which are provided with gatings or slots'B and C for the reception of the stumps V and D on the bolts L and J respectively so that the tumbler or tumblers A will simultaneously.-.enga'ge and release the two bolts J i and L. By this construction, when the inside" bolt J has been protracted, as shown more particularly in Figs. 2 and 11, by means of a guest key W inserted through the inside keyhole K, the emergency key X may be inserted from the outside of the lock and rotated to 'disengagethe' tumblers from the stumps V and D and protect the outside bolt L. As has been'already shown,-the protraction of the outside bolt QL will retract through the lever'M the inside bolt J. The

outside bolt L may thenberetracted by the emergency key X without disturbing the inside bolt J, and the door will .beunlocked.

When the door is unlocked, and it is desired tolockit from the inside the bolt J is. protracted by the guest key WV. In this operation the stump D on the inside bolt will take a position over theshoulder S on the ward'S so that said ward. will be prevented from upwardfmovement. Hence the operationof the outside bolt L by. a'guest key or master key inserted in the outside keyhole will be prevented, a inasmuch as the guest key and master key are not bitted topass' the locked ward. Access may still be had to the room by the proprietor or other possessor of the emergency key, as the emer- 1 ed out, prevents the retraction of the outside gency key is bitted to pass the ward and is therefore operative to protract the outside bolt. This will cause the operation-of the connecting lever in such a manner as to retract the inside bolt, after which the outside bolt may be retracted independently, and the door will be unlocked, as above explained. When the proprietor or other anthorized person desires tolock the door from the outside against the use of the guest key W the emergency key X may be inserted from the outside of the lock and may protract the outside bolt L without in any way moving the ward S so that when the bolt is protracted the stump V will engage the check U and prevent the ward S from being lifted. This construction, as already pointbolt L by the guest key W or master key IV.

Each of the tumblers A is shown provided with a spring E which engages a post F in the case, and is adapted to return the tumblers to their lower or normal position.

The lever M is is swung into the path of rotation of the bit H of the key, as shown more particularly in Figs. 2 and 11 to prevent the Withdrawal of the key when the bolt J is protracted.
